The GRACO 77X300 Electric Dyna-Star HP Pump System is an electric piston pump designed for automatic lubrication systems. It features a steel reservoir with a dip stick and is available with either a 35 lb (16 kg) or 60 lb (27 kg) capacity. The system is intended for continuous, reliable lubrication of heavy-duty equipment, helping to reduce component failures and extend equipment life.

Key Features:

• Electric piston pump
• 77X300 (35 or 60 lb / 16 or 27 kg reservoir)
• Steel reservoir, buna-n rubber wetted parts
• Maximum working pressure: 3500 psi (24.1 MPa, 241 bar) with vent valve installed; up to 5000 psi (34.4 MPa, 344 bar) without vent valve
• Single line parallel metering devices; in-plant machinery, off-road equipment, on-road vehicles
• IP69K (ingress protection)
• Dip stick for easy reservoir level monitoring
• Low level signal capability
• Follower plate for efficient grease dispensing
• Heavy-duty gear drive (GRACO Advantage Drive™)
• Motor control for speed and AMP management
• Cold weather performance (-40°C)
• Efficient seal replacement
• Reliable, continuous lubrication

Applications:
Automatic lubrication for heavy-duty construction, mining, agricultural, and industrial equipment. Suitable for environments requiring robust, reliable, and continuous lubrication to prevent component failures.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper alignment and secure mounting of the pump system
• Connect to compatible single line parallel metering devices
• Verify reservoir size and capacity for intended application
• Follow manufacturer guidelines for electrical connections and safety
• Regularly check and maintain reservoir and pump components for optimal operation
• Monitor grease level using the dip stick
• Inspect and replace seals as needed
• Check for leaks and proper function of the low level signal
• Clean and inspect the system regularly to prevent contamination
